Reducing texture storage is advantageous because of the smaller memory capacity of many embedded systems compared to desktop systems. Smaller textures also provide a welcome performance advantage since embedded platforms typically provide less performance than desktop systems. S3TC compressed textures are widely supported and used by applications. The DXT1 format is used in the vast majority of cases in which S3TC compressed textures are used. However, EXT_texture_compression_s3tc specifies functionality that is burdensome for an OpenGL-ES implementation. In particular it requires that the driver provide the capability to compress textures into S3TC texture formats, as an S3TC texture format is accepted as the parameter of TexImage2D and CopyTexImage2D. Further, EXT_texture_compression_s3tc may require conversion from one S3TC format to another during CompressedTexSubImage2D if the parameter does not match the of the texture image previously created by TexImage2D. In an OpenGL-ES implementation it is therefore advantageous to support a limited subset of EXT_texture_compression_s3tc: Restrict supported texture formats to DXT1 and restrict supported operations to those that do not require texture compression into an S3TC texture format or decompression from an S3TC texture format.
